DISCUSSION AND OUTLOOK
----------------------
At 900 AM CST (1500 UTC), the center of Tropical Depression
Eighteen-E was located near latitude 12.7 North, longitude 98.6
West. The depression is moving toward the west-northwest near 5 mph
(7 km/h). A west-northwestward motion with an increase in forward
speed is expected during the next few days.
 
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Steady strengthening is forecast during the next few days.  The
depression is expected to become a tropical storm later today, and
it is forecast to become a hurricane by Tuesday.
 
The estimated minimum central pressure is 1006 mb (29.71 inches).

Deep convection is gradually becoming better organized in
association with the depression.  There is evidence of banding over
the northern and western portions of the circulation, although
there appears to be some easterly shear over the system.  TAFB
provided a Dvorak classification of T2.5/35 kt and objective
estimates are in the 30-35 kt range.  Given the fragmented nature
of the convective banding, the initial intensity is held at 30 kt.  
A very recent arriving WSF-M microwave overpass was very helpful 
in locating the center, which was a little north of the previous 
estimate.

The initial motion appears to be 295/4 kt, a little slower than 
estimated in the first advisory.  The depression is forecast to 
move faster toward the west-northwest, to the south of a 
deep-layer ridge over Mexico during the next several days.  The 
track guidance is in good agreement on the core of the system 
staying well south of the coast of southern Mexico, and the NHC 
track forecast follows a blend of the GDM consensus aid and the HFIP 
corrected consensus.  The new track was adjusted slightly north of 
the previous advisory due to the more northward initial position.
 
Moderate easterly shear over the system is likely to keep 
significant strengthening in check during the next 12 hours, but the 
system is likely to become a tropical storm during that time. By 
late tonight and Monday, a faster rate of strengthening is expected 
as shear decreases and the system moves over warm SSTs.  Much of 
the intensity guidance shows the system becoming a hurricane in 
about 48 hours, and the NHC wind speed forecast follows suit.  
Around 72 hours, there is some uncertainty with regards to SSTs 
with the track potentially moving over the cool wake of Hurricane 
Polo. Therefore, the intensity forecast during that period calls 
for the intensity to level off, which is similar to what is shown 
by the HFIP corrected consensus.
